Be it known that I, HENDRIK CORNELIS FARM, a subject of the Queen of: the N etherd lands,4 and a resident of Sidhoardjo, Soera- ,-baya, Island of Java, Dutch East Indies,

have invented anew and Improved Boiler Cleaner, of which the following is a full', clear,

Y and ,exact description.

This invention relates to boiler cleaners, and. is especiallyuseful `in connection with Water tube boilers. A

More particularly, the invention relates to a boiler cleaner having adjustable steam conduits rovided with a plurality of nozzles ar ranged to be directed toward the tubes of the boiler and permitting'the steam to escape in jets to remove the soot, ashes and other accumulations u' on the tubes, and further having means or introducing steam into`the conduits, and means for adjusting the conduits to direct the steam jets in diiferent directions, the conduits being located in recesses provided therefor inwalls of the boiler, to protect the conduits from the gases of combustion.

An object of the invention is to rovide a simple, strong and efficient boiler c eener for use in connection with lwater tube and other boilers, which can be manufactured inexpensively, and which can be applied to boilers of various forms of construction.

A further ob'ect of the invention is to provide a device oi the class described which has adjustable means for directin steam jets against the tubes of boilers, to ree the tubes from accumulations of soot, ashesl and the like, and which is arranged so that it is normally protected when not in use, fromthe burning gases in the boiler.

A sti l urther object of the invention is to provide a boiler cleaner' which is extremely rapid in operation, which can be controlled from the to of the boiler, so that in a batiiers can be arranged side by side, Without intervening s aces therebetween, and which can be use to clean the boiler tubes without interrupting the operation ol' the boiler.

The invention consists in the construction and combination of parts to be more fully described hereinafter and particularly setA indicate corresponding parts in all the views, andinwhichs-flv V Figure 1 is a longitudinal section foi awater tube *boiler having my invention., a lied thereto; Fig. 2 is a plan View of the cile-13j showing the arrangement offl the boiler cleaner; Fi 3 is an. enlargedV transverse section, on the 'ne 3--3 of Fig. 1o f a ortion of one of the: side wallsof the boiler, s owing in crosssection one of the steam-conduits and a nozzle; Fig. 4 "is an enlar ed longitudinal section of a detail 'of one o? the steamcon duits, and Fig. 5 is a perspective view show 4in a nozzle of modified form.

efore proceeding to a more detailed exg planation of my'invention, it should beunderstood .that lwhile the saine is particularly useful in connection with that type of boiler known as a Water tube boiler, it can also4 be 'advantageously applied toy other types of to prevent loss of heat, due to radiationlfrom the sides of the boiler. With many forms of Water tube boilers this cannot be done, as it is necessary to leave openings in the side walls and spaces at the sides, so that the banks of water tubes can be easily cleaned. My boiler cleaner is operated from the top of the boiler and thus ermits the boilers to be arranged side by si e Without intervening spaces, when located in batteries. Furthermore, th'e use of my boiler cleaner does not interfere With the operation of vthe boiler and thus neither time nor combustible is lost. It will be understood that if the boiler tubes are incrustecl with accunmlations oi soot or ashes, the efficiency of the boiler is lowered, and it is not only of advanta e but is often absolutel necessary, to keep t 1e tubes free from suc accumulations, especially for the generation of steam under high pressure.

Referring more particularly to the drawin s, A represents the side Walls of a Water tu e boiler, having, referably, al lining Af" of 'fire brick or the lile. The Walls may be fashioned from brick, masonry or anyother suitable material.

B represents the back wall of the boiler, and C the front thereof.

ico

The boiler includes the usual bank of Water tubes D arranged at an angle with the horizontal and connected at the opposite ends by means of headers D. The atter are joined by means of circulatintubes E with the Water and steam drums At the front of the boiler is the furnace G having the furnace wall G', the gratebars G and the ash-pit G3. The flame and gases of combustion from the furnace pass along the bank D of tubes, being 1suitably directed by baffle walls H, and subse uently escape from the boiler throu h the c lmney ilue I. Above the drums is the usual boiler top or roof J fashioned from brick, masonry or thelike.

In each of the side walls A, at the inside thereof, are elongated recesses A arranged at an angle with the horizontal, and at substantially ri ht an les to the len ths of the tubes of thegbank The roof o the boiler J has at the upper ends of the recesses A', openings J', closed by means of cover plates J held in4 osition by bolt clamps Ja. At the forward) edge 'of each of the recesses A is an inwardly extending lip A2 fashioned from re brick or other suitable material and preferably integral with the lining A3 of the wall A.

In each of the recesses A' is located an elongated steam conduit 1() consisting preferab y of a cast iron pipe and extending through a suitable opening 11 of the plate J. At the opening 11, the plate, at the in side has a neck 12 against which abuts a collar 13 adjustably mou'ited upon the conduit by means of a set screw 14. The collar serves to prevent the upward movement of the conduit though leaving it free to turn. At the lower end each of the conduits has a stud 15, pivotally carried by a plate 16 mounted near the bottom of the recess A. The section 10 of the conduit adjacent to `the bank D of tubes, has a series of lateral extensions 17 provided with outlet openings 18. At the outer ends, the extenslons 17 are interiorly threaded and receive the correspondingly threaded ends of nozzles 19 of any preferred or common form, and serving to permit the escape of steam from the conlduit 'in jets. The nozzles are so arran ed that by suitably adjusting the conduits t ey can be directed between the tubes of the bank D so that the steam escaping from the nozzles can blow away the accumulations upon the tubes. f At the up er end of each of the conduits 10 is forme a laterally extended flange 20 upon which is a head 21 having a ilange 22 engaging the iiange and secured thereto by means of bolts 23 or in any other con venient manner.YY Between the anges, if i necessa may be provided a gasket 24. The hea 21 has an opening 25 therethough,

`pipe an registering with the top A tube 26 has the end inserted in the opening of the head and carries a stuffing-box gland 27 provided with a Harige 28 and movable into an annular recess 29 of the head. The recessv 29 contains suitable packing 30. Bolts 31 having threaded extremities arranged in correspondingly threaded openings 32 of the head are arranged in openings of the liange 28 and carry nuts 32 by means of 'which the gland 27 canbe adjusted so that a `steam and water-tight fit between the head 21 and the tube 426 can be effected. At the sides, the head 21 has openings 33 in which can be inserted the end of a rod 34 by means of which the head and the conduit 10 can be turned and adjusted.

Each tube 26, above the head 21, has a valve 35 by means of which the flow of steam through the tube can be regulated. The tubes 26 of all the conduits 10 communicate with a common pipe 36 connected with the steam dome K of the boiler, through a connection 37 having a valve 38, by means of which the flow of steam therethrough can be controlled.

The arrangement is such that the conduits 10 are at substantial] 1 right angles to the lengths of the tubes oi the bank D, so that when the conduits are adjusted, the nozzles 19 can be directed squarely between the tubes to blow the accumulation therefrom. When not in use the conduits can be adjusted to swing the nozzles into the recesses A which serve to rotect them from contact with the flame andl gases of combustion, the lips Az of the recesses assisting to protect the conduits and the nozzles.

Having thus described my invention, I
